Member Function Documentation

FFT_finalize_Target()

void FFTAcceleration_2wayM2L_fftw::FFT_finalize_Target ( FFTAccelerableExpansion &  Expansion, double  radius  )

virtual

Finalize a Target expansion by adding the result of the M2L stored in Fourier space to the expansion values.

Include the rescaling using the radius parameter, should be the same as the one used by FFT_initialize_Source

Parameters

FFTAccelerableExpansion	& Expansion
double	radius

Implements FFTAccelerationAPI.

FFT_initialize_Source()

void FFTAcceleration_2wayM2L_fftw::FFT_initialize_Source ( FFTAccelerableExpansion &  Expansion, double  radius  )

virtual

Initialize a source expansion's FFTDatacontainer, including rescaling using the radius parameter (see doc/Rescalling)

Parameters

FFTAccelerableExpansion	& Expansion
double	radius

Implements FFTAccelerationAPI.

FFT_initialize_TransferFunction()

void FFTAcceleration_2wayM2L_fftw::FFT_initialize_TransferFunction ( FFTAccelerableExpansion &  Expansion )

virtual

Initialize a source expansion's FFTDatacontainer, all subsequent transformations (flip of the matrix or rescaling of scaling blocks for example) should be done here.

Parameters

FFTAccelerableExpansion

& Expansion

Implements FFTAccelerationAPI.
